Fluent Inc., world leader in computational fluid dynamics (CFD) software and services, announced today that its unique RSolve TM Remote Simulation Facility (RSF), an online service for running FLUENT 6.2, has expanded its high performance computing facility to over 200 Peak Mflops, with 64 Gbytes of memory and 1.6 Terabytes of storage. In addition, the entry price for using the RSF has been reduced by a factor of 3x to a range of $US6/CPU-hr - $US3/CPU-hr, depending on volume of purchase.

The benefit of Fluent's RSolve service lies in its ability to provide cost effective access to the Fluent application for CFD users who have a periodic need to perform large computationally intensive simulations. By capitalizing on Fluent's in-house Linux cluster expertise, users can immediately begin performing complex flow modeling on an optimized solution, instead of facing the long and often complex hardware and software procurement issues they might otherwise encounter.

I have a problem in solving two coupled charge density and potential equations. It is related to corona discharge and I have two boundary conditions i.e at electrode and at collector. The potential is known. So can any one help me to solve this problem? I am doing the numerical work using fluent software and I need to compare the potential and charge density distribution with the analytical solution where in I am getting 2 different solutions for charge density.

Since as much as 75% of a typical product's lifecycle cost is determined during the initial design phase, the return on investment for upfront analysis should be the highest.

Unfortunately, many companies struggle to leverage their valuable design experience while protecting intellectual property, or work hard to develop sophisticated methods with Computer Aided Engineering (CAE) software but fall short of realizing their true potential to impact designs.

How do you capture and protect your companies design expertise, and apply it consistently design after design?

How can you make better use of powerful analysis software early in design when its impact is greatest?

NIKA GmbH, the leading provider of fluid flow and heat transfer simulation software for engineers, announced that Siemens AG has signed a worldwide agreement for licensing its family of Engineering Fluid Dynamics (EFD) products. Under the terms of this agreement, all Siemens facilities will be able to acquire NIKA analysis products under preferred terms.

Siemens chose EFD.Lab and EFD.V5 for their accuracy, efficiency, ease-of-use and low cost of ownership. EFD.Lab is an industry leading fluid flow and heat transfer simulation program while EFD.V5 offers a seamless integration between Dassault Systèmes’ CATIA V5 and NIKA’s analysis technology.

My colleages and I (research students) are thinking of solving the unsteady incompressible 3D NS eqns codes to model flapping wings. Hence, the boundary will be moving. We've been looking thru many schemes and we need some opinons...

Projection or fractional or artificial compress, SIMPLER which is more suitable? We're a bit confused.

2nd order crank Nicolson or backward Euler for time discretization?

How to move the boundary? What we know is to rotate the whole grids, suggested by Liu & Kawachi. Is there a better solution?

We'll be using structured grids. Is it better to write ourselves or get a ready program? Is it efficient to generate 2d grids and stacked them together?
